Air conditioner fan turns on and off

An air conditioner fan is an essential device in our daily lives. It plays an important role in distributing fresh air and improving air quality in homes or offices. Its main function is to circulate air and direct it toward the target space, which helps provide comfort and reduce environmental temperature. However, we may sometimes encounter the problem of the air conditioner fan turning on and then turning it off after a short period of time, which causes frustration and makes us search for a solution to this problem.

The outdoor unit fan turns on and off.

If your outdoor air conditioner fan turns on and off repeatedly, this could indicate a problem that needs to be fixed. There could be several possible causes for this problem, and it's important to check and address them quickly to avoid bigger problems with the system.

Blockage in the fan or condenser: There may be a blockage in the fan or near the condenser, causing the unit to overheat and stop. Make sure that there are no objects or dust obstructing the fan’s movement and that the condenser is clean.
Freon level problem: Low Freon levels may be another reason for the outdoor unit fan to turn on and off. You should contact a qualified technician to inspect the cooling system and top it up with Freon if necessary.
